When you drag an object from the Data tab into the Query Filters panel, before you let go of the mouse, note how it looks in the destination area:

If there is a solid line above it separating it from the object(s) that precedes it, it will insert at the same level as the objects above it.

If you slide your mouse up a little (before you release the object!), you'll see the screen change: the object above where you are turns into a blue rectangle, with a white rectangle below it, and both are indented a little, indicating the object you are inserting and the object above it will together be indented. You can do multiple levels of indents - it just takes a little practice.

 

Once you have the filters indented the way that you want them, double-click on the AND to turn it to an OR (and visa versa).
